Don't allow your toddler snack between meal times. By taking out snacks, you are making your child eat what you know is good for them. Your child will not starve if they donât get a biscuit twenty minutes before their tea. All they will do is fill up their little tummy and not eat any good food.
The two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase âeither cytosine (C), guanine (G), adenine (A), or thymine (T)âas well as a monosaccharide sugar called deoxyribose and a phosphate group.he two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides.

The DNA molecule consists of two polynucleotide chains in the form of a double helix, containing phosphate and the sugar deoxyribose and linked by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine.ach rung is made up of two chemical bases, called nucleotides, that are joined together by hydrogen bonds. There are four kinds of nucleotides in a DNA molecule: cytosine, guanine, adenine, and thymineâC, G, A, and T, for short.
